Multi-layer bonding composite three-dimensional fabric foundation pit waterproof curtain supporting structure and construction method thereof
The invention relates to the technical field of building construction, in particular to a multi-layer bonding composite three-dimensional fabric foundation pit waterproof curtain supporting structureand a construction method thereof. The multi-layer bonding composite three-dimensional fabric foundation pit waterproof curtain supporting structure comprises a plurality of cast-in-situ bored piles and foundation pit connecting parts arranged among the cast-in-situ bored piles and used for connecting the cast-in-situ bored piles; the plurality of cast-in-situ bored piles are uniformly arranged atintervals; and each foundation pit connecting part comprises a strip-shaped foundation trench and a reinforcement cage arranged in the strip-shaped foundation trench, and a plurality of layers of composite three-dimensional fabrics are horizontally arranged in the reinforcement cage; The piles are connected into a whole through the composite three-dimensional fabrics and reinforced concrete, thestrength is improved, and the water stop performance is enhanced; the water stopping capability is improved by about 30%; and the supporting strength of the cast-in-situ bored piles is improved by 15%-20%; Compared with a large-volume concrete structure, the used composite three-dimensional fabric has the advantages that the use amount of concrete is saved, the construction cost is reduced by about 10%, and the environment is improved; and epoxy asphalt is used as an adhesive of each layer of three-dimensional fabric, so that the composite three-dimensional fabric is endowed with relatively strong water stop performance and bonding stability.
本发明涉及建筑施工技术领域，特指一种多层粘接复合立体织物基坑止水帷幕支护结构及其施工方法，包括若干个钻孔灌注桩、以及设于若干个钻孔灌注桩之间并用于连接若干个钻孔灌注桩的基坑连接部；若干个钻孔灌注桩均匀间隔设置；基坑连接部包括条形基槽、设于条形基槽内的钢筋笼，钢筋笼内水平设有多层复合立体织物；本发明利用复合立体织物与钢筋混凝土将桩与桩之间连接成整体，提高了强度又加强了止水性能；提高其止水能力约30％；提高了钻孔灌注桩支护的强度15‑20％；所使用的复合立体织物相较于大体量使用混凝土结构，节约了混凝土使用量，减少造价约10％，改善环境；利用环氧沥青做每层立体织物的粘接剂，赋予了复合立体织物较强止水性能与粘接稳定性。
